Repeated evolution of underwater rebreathing in diving Anolis lizards

open access: yesCurrent Biology, 2021
Air-based respiration limits the use of aquatic environments by ancestrally terrestrial animals. To overcome this challenge, diving arthropods have evolved to respire without resurfacing using air held between their cuticle and surrounding water.1-4 ...

Conservation and Convergence of Genetic Architecture in the Adaptive Radiation of Anolis Lizards

open access: yesbioRxiv, 2021
The G matrix, which quantifies the genetic architecture of traits, is often viewed as an evolutionary constraint. However, G can evolve in response to selection and may also be viewed as a product of adaptive evolution.

Cell Surface Xyloglucan Recognition and Hydrolysis by the Human Gut Commensal Bacteroides uniformis

open access: yesApplied and Environmental Microbiology, 2021
The omnipresence of xyloglucans in the human diet has led to the evolution of heterogeneous gene clusters in several Bacteroidetes species in the HGM, each specially tuned to respond to the structural variations of these complex plant cell wall ...

A biogeographic reversal in sexual size dimorphism along a continental temperature gradient [PDF]

open access: yes, 2019
© 2018 The Authors The magnitude and direction of sexual size dimorphism (SSD) varies greatly across the animal kingdom, reflecting differential selection pressures on the reproductive and/or ecological roles of males and females.

A highly conserved ontogenetic limb allometry and its evolutionary significance in the adaptive radiation of Anolis lizards

open access: yesProceedings of the Royal Society B, 2021
Diversifications often proceed along highly conserved, evolutionary trajectories. These patterns of covariation arise in ontogeny, which raises the possibility that adaptive morphologies are biased towards trait covariations that resemble growth ...

Population Physiology, Demography, and Genetics of Side-Blotched Lizards (\u3cem\u3eUta stansburiana\u3c/em\u3e) Residing in Urban and Natural Environments [PDF]

open access: yes, 2023
Wildlife populations across the globe are poised to lose their natural habitat to urbanization, yet there is limited information on how different species handle living in cities.

Safety Assessment of Bacteroides Uniformis CECT 7771, a Symbiont of the Gut Microbiota in Infants

open access: yesNutrients, 2020
The formulation of next-generation probiotics requires competent preclinical studies to show their efficacy and safety status. This study aims to confirm the safety of the prolonged oral use of Bacteroides uniformis CECT 7771, a strain that protected ...

Macroevolution of microhabitat, climate, and morphology in lungless salamanders (Family: Plethodontidae). [PDF]

open access: yes, 2020
Biologists have long sought to understand how ecological selective pressures drive evolutionary responses. Defining how morphology, life history, and abiotic conditions interact across deep time can reveal the selective pressures responsible for shaping ...

Diversidad y conservación de anfibios y reptiles en un área protegida privada de una región altamente transformada en el sur de Veracruz, México [PDF]

open access: yes, 2020
El establecimiento de Áreas Protegidas Privadas (APPs) es una de las estrategias para la protección de la biodiversidad ante la modificación del hábitat en bosques tropicales; sin embargo, su importancia en conservación ha sido poco evaluada.

Thermal Tolerance, Physiology, and Microhabitat Use of Eleutherodactylus Coqui Across an Elevational Gradient in Hawai‘i [PDF]

open access: yes, 2023
The coqui frog (Eleutherodactylus coqui) is an invasive species in Hawai‘i, and has spread across much of the island. While elevational temperature differences are thought to restrict the coqui’s spread, it is unclear if they have resulted in changes to ...
